| Abstract | ||
| This study involves nano-materials addition and interaction with cement mortar behavior for many mortar samples under variable curing time with constant water to cement ratio (W/C = 0.5). In this research some properties such as (hardness and water absorption test), were affected by adding small ratios of nano-particles (SiO2 or Al2O3) as replacements to the Ordinary Portland Cement (OPC) / type (I). The percentages of nano materials additives replacement on the mixture of mortar include (1, 2, 3, 4 and 5%) for both nano materials with constant (W/C) ratio. Also the amount of the fine aggregate used was three times the amount of cement. The results showed that, the hardness of the mortars for both nano materials gives better properties than mortar without nano materials in all tests. Best enhancements in properties for mortars with nano silica were achieved with (3%) additives while were achieved with nano alumina at (2%) additives. | ||
